It happens, even to the best of us! Creative Block is a real thing. I'd first like to say, it's okay. Don't be afraid of it. Sometimes we need a mental and/or physical break. Our minds tire just as our bodies do. Sometimes our lack of creative thought is a message from our mind's eye that we need a mental break. Listen to it. The first step to getting out of this slump is to step away and relax your mind.
